btrfs-progs: canonicalize pathnames for device commands
mount(8) will canonicalize pathnames before passing them to the kernel.
Links to e.g. /dev/sda will be resolved to /dev/sda. Links to /dev/dm-#
will be resolved using the name of the device mapper table to
/dev/mapper/<name>.
Btrfs will use whatever name the user passes to it, regardless of whether
it is canonical or not. That means that if a 'btrfs device ready' is
issued on any device node pointing to the original device, it will adopt
the new name instead of the name that was used during mount.
Mounting using /dev/sdb2 will result in df:
/dev/sdb2
209715200 39328
207577088 1% /mnt
lrwxrwxrwx 1 root root 4 Jun 4 13:36 /dev/whatever-i-like -> sdb2
/dev/whatever-i-like
209715200 39328
207577088 1% /mnt
Likewise, mounting with /dev/mapper/whatever and using /dev/dm-0 with a
btrfs device command results in df showing /dev/dm-0. This can happen with
multipath devices with friendly names enabled and doing something like
'partprobe' which (at least with our version) ends up issuing a 'change'
uevent on the sysfs node. That *always* uses the dm-# name, and we get
confused users.
This patch does the same canonicalization of the paths that mount does
so that we don't end up having inconsistent names reported by ->show_devices
later.

This patch adds functionality (in qgroup-verify.c) to compute bytecounts in
subvolume quota groups. The original groups are read in and stored in memory
so that after we compute our own bytecounts, we can compare them with those
on disk. A print function is provided to do this comparison and show the
results on the console.
A 'qgroup check' pass is added to btrfsck. If any subvolume quota groups
differ from what we compute, the differences for them are printed. We also
provide an option '--qgroup-report' which will run only the quota check code
and print a report on all quota groups. Other than making it possible to
verify that our qgroup changes work correctly, this mode can also be used in
xfstests for automated checking after qgroup tests.
This patch does not address the following:
- compressed counts are identical to non compressed, because kernel doesn't
make the distinction yet. Adding the code to verify compressed counts
shouldn't be hard at all though once kernel can do this.
- It is only concerned with subvolume quota groups (like most of

btrfs-progs: clarify mkfs.btrfs --alloc-start option
Fedora had a bug where a poor user thought that --alloc-start
meant that the filesystem would be created at that offset into
the device, rather than just starting allocations at that offset.
A subtle difference, but worth clarifying, because the manpage
is misleading on this point.
The original commit log for this option says:
Add mkfs.btrfs -A offset to control allocation start on devices
This is a utility option for the resizer, it makes sure to allocate
at offset bytes in the disk or higher. It ensures the resizer will have
something to move when testing it.
so allude to that intended use in the manpage.
